To all whom may concern:

Be it known that We, Zrnxnnns FINKEL and IRA Conny, citizens of theUnited States, and residents of Seattle, in the county of King and Stateof Washington, have invented certain new and useful Improvements inSteam Pressing-Machines, of

-which the following is a full, true, and eX- act specification.

Our invention relates to improvements in steam pressing machines, andhas for its principal object to provide an improved and simplifiedportable steam pressing machine in which electricity is used as a'heating agent for vaporizing the water and heating the pads.

In the usual pressing machine, it is necessary to locate the machinepermanently in one place due to the necessary gas and water pipingconnections. In our machine, no gas is used, and no Water connectionsare necessary; The better control of and more uniform heating byelectricity makes it preferable to gas.

Other objects will appear as our invention is more fully explained inthe following specification, illustrated in the accompanying drawingsand pointed out in the appended claim.

In the drawings Figure 1 is a front elevation of our device. Fig. 2 is apart end elevation of Fig. 1. Fig. 3 is a detail of the headconstruction. Fig. 4 is a fragmentary side elevation of Fig. 1 showingthe treadle mechanism.

In referring to the drawings numeral 1 indicates a frame to which issecured the usual Work table 2,. A buck 3 is secured to frame 1 in theusual manner and position as is connnon in machines of this class.Hinged above the buck 8 is head i which folds down on to the buck whenoperating. The head and buck are usually padded on their working facesto facilitate pressing.

In our improved pressing machine the head is formed of an inclosed tank5 having a large number of fine perforations 6 in its lower side. Thetop and edges of the tank are protected by an insulation 7 against heatloss. Insinc and adjacent the lower side of the tank is a perforatedsliding plate 8, the perforations being spaced the same as perforations6, but normally out of register with said perforations 6. Springs 9along the edge of the tank hold the plate o uuwn against the lower sideof the tank. Plate 8 is shifted, so that the perforations register withperforations 6, by links 10 one end of which are pivotally fastened tothe plate and the other end to boil crank levers 11 which in turn aresecured to a shaft 12. Shaft 12 projects through the edge of tank and isprovided ,With a handle 18. The turning of handle 13 slightly shifts theplate 8. Water tank 14; is mounted on head 4 and has a connection 15intotank 5.- The connection 15 has a back pressure valve 16 in it forthe purpose of regulating the flow of Water. Head 4 is raised andlowered by a foot lever 17 and connections 18. A spring 19 normallyholds the head in a raised position. Tank 5 electrically operatedheating coils22 inside of it, and a cord attachment 21 for connection toa power socket.

A small amount of Water admitted to the tank 5 is converted into steamby the heat ing coils 22 and when the head'is brought into contact witha current on buck 3, the lever 13 is operated to allow the steam to passout onto the padding of the head as i necessary in steam pressing.

.The buck may be heated if desired 1n a similar manner to the head.

While We have shown a. particular form of embodiment of our invention,We are aware that many mlnor changes therein Will readily suggestthemselves to others skilled v in the art Without departing from thespirit and scope of the invention, and We therefore desire to avoidbeing limited to the exact form shown and described.

Having described our invention, What We claim as new and desire toprotect by Letters Patent, i

In a steam pressing machine including;' a frame and buck, thecombination of a steam generating head hinged to said frame; said headincluding a tank with aperforated hottom, a similarly perforated plateWithin said tank and normally covering the peri'orations of said tank,means for moving said plate until the perforations of said plate andtank register, whereby the steam generated in the head is released whenthe holesare in register.
